4. Device Check
When parts are replenished or changeover takes place devices that have been
set can be verified, one by one on the display in order to prevent parts from
being mounted incorrectly. This function is referred to as device check. It is
also possible to set this function such that operation does not begin again until
every device has been checked.
4.1 Method and Function
There are two methods of carrying out the device check function. Device
check can be performed on the machine using the command keys or it can
be done with the use of the [PARTS SET] CANCEL/COMPLETE switch.
4.1.1 Performing Device Check on the Machine
The device check function can be made mandatory with the
commencement of automatic operation or it can be carried out as a
command key operation. When device check is to be made
mandatory with the start of automatic operation, the Proper data
item 70: Device Check SW must be set to either "Parts", "Miss", or
"Error". When device check is carried out as a command operation,
setting values in Proper data is not necessary.
When a mandatory device check is carried out with the start of
automatic operation, device check is carried out in accordance with
the setting made in Proper data item 70: Device Check SW.
Furthermore, anytime the production program is changed, device
check is carried out when automatic operation begins again.
Operation is not possible until the device check is completed.
To perform device check as a command operation on the machine
press the following command keys;
[Program] → [Device] → [Check]
Note: For information concerning the command operation procedure
refer to Part 3, "FCP IV-3 Commands".

4.1.2 The [PARTS SET] CANCEL / COMPLETE Switch
The [PARTS SET] CANCEL/COMPLETE switch is used as a final
check switch once the parts set operation is complete. When this
switch is set to "COMPLETE" production becomes possible and the
resupplied device table will move to its part picking position.
On the other hand, if for some reason the device table in the
resupply position is not to be moved to its part picking position
even though the parts set operation is complete, then this switch
can be set to "CANCEL" to prevent the table from being used in
production.
This switch is only enabled when the device table is in its resupply
position. This function does not work when the device table
designated as the original table is in its part picking position.
This switch works differently depending on whether the device
check function is used or not. This difference is explained next.

1. When the device check function is not used
In this case production becomes possible with the device table
in question when the switch is set to "COMPLETE." The signal
tower on the rear fence will begin flashing.
On the other hand, if the switch is set to "CANCEL" then
production with the device table in question will not be
possible. The signal tower on the rear fence will be lit.
2. When the device check function is used
In this case when all devices have been checked and the switch
is set to "COMPLETE", production becomes possible and the
device table moves from its resupply position to its part
picking position.
If the switch is set to "CANCEL" the machine remains in device
check mode and production with that table is not possible. The
signal tower on the rear fence will be lit.
To operate in the device change mode the status of one of the
tables, either table 1 or table 2, must be ready for production.
Also note that to operate in the changeover mode it is necessary for
the original table to be ready for production.
In the case where operation is not possible because neither table is
ready for production, the message "Parts are unset" will display
and the machine will wait for the [PARTS SET] switch to be set to
"COMPLETE".
